Sydney: Having won the Allan Border Medal for Best Cricketer of the Year, Australia`s cricket captain Michael Clarke is now hoping to surpass his top score of 329.

Clarke said on Tuesday that the 329 against India had allowed him to tick off a big career goal.

He said he had set himself three major goals - to ensure his fitness was at a very high level, to start well as Test captain and score a Test double-century.

He believed he had achieved all three.

"I as fit as I`ve ever been in my career. I think my captaincy`s started pretty well because I had the experience under Ricky Ponting as vice-captain," Clarke told reporters.

"And my goals personally, to score my highest Test score was one of those goals.

"I hadn`t scored a double hundred for Australia yet and that was something I wanted to achieve this summer," Clarke said.

But Clarke said he still had plenty to achieve on both a personal and team level and still believed he could improve as a batsman.

He also said there were some major challenges coming up for Australia as they sought to again become cricket`s dominant side, notably playing India in India, South Africa at home and England both home and away.
